New Siberian Islands

New Siberian Islands. The New Siberian Islands are a vast archipelago located in the Arctic Ocean, between the Laptev Sea and the East Siberian Sea. Administratively part of the Sakha Republic of Russia, the islands are renowned for their extensive deposits of Pleistocene mammoth tusks and bones, and for being a key site in the exploration of the Northern Sea Route.

Geography

The archipelago consists of three main subgroups: the Anzhu Islands to the south, which include the large islands of Kotelny Island, Faddeyevsky Island, Bunge Land, and New Siberia; the Lyakhovsky Islands closer to the mainland coast; and the De Long Islands to the northeast, including Jeannette Island, Henrietta Island, and Bennett Island. The landscape is dominated by flat, low-lying tundra and permafrost, with the highest point being Malakatyn-Tas on Kotelny Island. The geology features significant Quaternary deposits, with prominent coastal exposures like the Berelekh site revealing abundant Ice Age fossils. The climate is severe Arctic, with the surrounding seas covered by pack ice for most of the year.

History

The islands were likely sighted by Yakut hunters and Pomors in the early 18th century. The first recorded exploration was conducted by the Yakov Sannikov expedition in 1805-1806, leading to the discovery of Faddeyevsky Island. Further significant mapping was carried out by Pyotr Anjou during the 1821-1823 Ust-Yansk expedition. The archipelago gained fame in the 19th century as a major source of mammoth ivory, attracting commercial expeditions. The northeastern De Long Islands were discovered by the ill-fated 1879-1881 Jeannette Expedition led by George W. De Long. In the Soviet era, the islands became sites for polar stations and research, with notable work by figures like Baron Eduard von Toll, who disappeared during an expedition in 1902.

Administration

The archipelago falls under the jurisdiction of the Sakha Republic, a federal subject of the Russian Federation. It is part of the Bulunsky District, one of the largest and most sparsely populated administrative regions in the world. Sovereignty over the islands, and the surrounding maritime areas, is maintained by the Border Service of the FSB, with the nearest major administrative center being the port town of Tiksi on the mainland. The islands are included within the security and operational remit of the Russian Northern Fleet and are considered strategically important for monitoring the Arctic region.

Fauna and Flora

The ecosystem is characteristic of the high Arctic, with vegetation consisting of mosses, lichens, Arctic poppy, and sparse grasses. The terrestrial fauna includes Arctic fox, reindeer of the Siberian subspecies, and occasional visits by polar bears across the sea ice. The coastal waters and polynyas are vital for marine mammals such as the walrus, bearded seal, and ringed seal. The islands are a significant breeding ground for migratory birds, including snow bunting, various species of seabird like the black guillemot, and are located along the flight path of the snow goose. The Bennett Island area is known for its population of ivory gull.

Economy and Infrastructure

Economic activity has historically centered on the extraction of mammoth ivory, though this is now limited and seasonal. There is no permanent population; temporary inhabitants are primarily military personnel, border guards, and researchers operating from a few isolated stations, such as the one on Kotelny Island. This station, originally established during the Soviet Union era, serves as a key logistical hub for the Russian Armed Forces in the Arctic. The islands' strategic location along the Northern Sea Route makes them important for navigation, meteorological observation, and as a base for projecting sovereignty. There are no commercial ports or airports, with access dependent on icebreaker ships and military aviation.
